EDWARD POHL, OF PATERSON, NEW JERSEY.

SILK-THEE AD-FITEIISHING- MACHINE To all whom it may concern:

Be it known that I, EDWARD Form, a subject of the Crown of Austria, anda resident of Paterson, county of Passaic, State of New Jersey, haveinvented certain new and useful Improvements in Silk-ThreadinishingMachines, of which the following is a specification, reference being hadto the accompanying drawings, forming a part thereof.

My invention relates to improvements in si k thread finishing machines,and particularly to means in which said threads are treatedindividually, as distinguished from appliances in which the threads aretreated in bulk such as in skeins. In apparatus of this character thethreads are first passed through a finishing solution, and are thencarried over a heated contact surface, with the result that they aredried, ironed and lustered. Finally they are wound up upon spools bymeans of suitable winding mechanism. he heated contact surface in thisclass of machine is usually a flat horizontal steam heated table, beingof sufficient width to support and enga e all of the threads treated inany particu ar machine.

In the resent form of machine I provide an individual contact member foreach thread, such contact member being in the form of a verticallydisposed tube preferably polygonal in cross section. The thread iscarried longitudinally down one side of this member and up the oppositeside thereof, and the said member is arranged to be turned axially fromtime to time, whereby as one set of surfaces becomes fouled, a new setof sur faces may be brought into operation without stop ing the machine.A number of these tubu lar members are arranged side by side in a row,and the surfaces employed are to the left and right of an operatorstanding facing the members, so that both the downgoing portion of thethread and the upgoing portion thereof are visible to the operator andimmediately accessible to him. I also provide means whereby thereturning end of the thread is caused to travel laterally across thesurface of the contact member, so that a rolling or twisting action maybe given to the thread in order that the same may be polfished andlustered uniformly on all sides.

My invention also consists in many novel details of construction andcombinations of parts as will hereinafter be more fully set forth, andin order that my invention may be thoroughly understood, I will nowproceed to Specification of Letters Patent.

describe an embodiment thereof, having reference to the accompanyingdrawings illustrating the same, and Will then point out the novelfeatures in claims.

In the drawings: Figure 1 is a view in side elevation of a portion of amachine embodying my invention, a large portion thereof being brokenaway in order to save space, said broken away portion, however,containing mechanism which is in the main a mere duplication of themechanism illustrated. Fig. 2 is a view in vertical transverse sectionthrough the machine. Fig. 3 is a detail view in partial side elevationand partial vertical section, on an enlarged scale, of one of thecontact members and certain correlated parts. Fig. 4 is a similar viewat right angles thereto. Fig. 5 is a detail sectional view thereof uponthe line 55 of Fig. 3. Fig. 6 is a detail top view showing particularlytake up mechanism for one of the threads. Fig. 7 is a detail top viewshowing particularly the let-off mechanism for one of the threads andthe means for applying solution thereto.

The frame of the machine comprises a plurality of standards 10, alongitudinal top sill 11, a middle sill 12, upper horizontal sidemembers 13, and lower horizontal side members 14 (see particularly Fig.2). The top sill 11 forms a support for laterally extending brackets 15upon either side thereof, said brackets arranged to support and carrybaths 16 for the solution. Each of said brackets 15 also supports andcarries bearing members 17 for a reel or bobbin 18, a solution applyingroll 19, a brush 20, an idler direction pulley 21, and guides 22, 22.

It may be here noted that, except for the driving mechanism, the machineas a whole is exactly alike upon opposite sides of the centrallongitudinal plane thereof, and that each side of the machine comprisesa plurality of similar mechanisms, each adapted to treat a thread orfilament.

Each of the upper and lower horizontal side members 13 and 14 carries aset of brackets 23 and 24 respectively, each pair of brackets 23 and 24constituting the support for a hexagonal tube 25 which constitutes thecontact member.

Referring more particularly to Figs. 3, 1 and 5, the brackets 23 and 24will be seen to be provided with projecting threaded portions 26 towhich is fitted a cylindrical tube 27. The hexagonal tube 25 is mountedloosely upon the said tube 27, as will be readily seen by reference tothe drawings; The lower bracket 24 ishollow and isprovided with a steaminlet pipe 28 and a nozzle 29 uprising therefrom and penetrating to theinterior of the tube 27 and with a discharge or outlet pipe 30. The saidpipes are arranged for the circulation of a heating medium such assteam, steam being conveniently admitted through the pipe 28 to theinterior of the tube 27, and the pipe 30 carrying ofi waters'ofcondensation therefrom. A direction pulley 3 1 is provided beneath thebracket 24, said direction pulley being arranged to revolve freely uponcone points or other bear ing members carried by the said bracket, thediameter of the said direction pulley being just about equal to thedistance between opposite faces of the contact member 25. The upperbracket 23 carries a direction pulley 32, the working face of which liesin substantially theplane of one ofthe surfaces of the said contactmember 25. The direction pulley 32 is preferably arranged to rotateabout a center eccentric to its working face, the result being that, asthe said pulley revolves,

the edge thereof works backwards and forwards in the plane of thesaidsurface, whereby a thread carried from the direction pulley 31 over thesaid direction pulley 32 and resting upon a contact surface of themember 25 Will be caused to 'move backwards and forwardsover thesaidcontact surface, as will be well understood.

, The middle sill 12 forms a support for brackets 34, which carrybearings 35 for take -up'rolls'or bobbins 36, and with brackets'37'which carry shafts 38provided with driving wheels 39. The'driving wheels39 engagefwhirls 40 carried by the said bobbins-36', whereby they may bedriven in the usual manner, The shafts 38 are connected together bysuitable gearing 41, and are drlven by means of a bevel gear connection42 and the-vertical shaft; 43, and another bevel gear connection 44 by afriction drive 45 through which variations of speed may be imparted, asmay be desired. Traversing thread guides 46 are supported by the upperhorizontal side members 13,.said traversing thread guides being drivenby means of a cam 47 and'gearing 48' connecting with one of theshafts-38, or by any other suitable means as may be convenient. 7

In operation the threads to be treated and wound'upon'rolls or bobbins18, are mounted in the machine by inserting the trunnions of the saidrolls or bobbins 18 in'the bearings 17. Each thread is then takenthrough a guide 22 over a solution applying roller 19, through anotherguide 22, over a brush 20, around a" direction roller or pulley 21, downover one of the surfaces ofa contact member 25', around" a bottomdirection roller" 31, up the opposite" contact surface of the member 25around an upper direction roller32, over a guiding element carried byone-of the'traversing guide bars 46, and on to a take-up bobbin 36. Therotation of the-shafts38'will rotate the bobbins 36, and, in winding upthe threads thereon, will" draw the-threads from the reels or bobbins 18over and across the mechanism just described. Each thread will receiveits solution from a roller 19, the excess solution being wiped off by abrush 20, and will be ironed, polished and lustered by means of thecontact member 25. The travel of the thread will cause the upperdirection roller 32 to rotate, and will thereby give the movement abovedescribed to the thread across the face of one of the contact surfacesof the member 25, this movement taking place, as it will be noticed,upon one side only of a mem ber 25, and to the greatest extent near thedischarge end thereof. This is advantageous as the thread, in coming tothe contact member quite wet, tends to foul the surface near theapproach end, and to attempt to rub the thread across a fouled surfacewould be to foul the thread. Further, the thread, in the first part ofits movement over the contact member, merely gets dried, while thepolishing and lustering takes place toward the latter part of suchmovement.

.It' is-while the polishing and lustering" is being effected that it isdesirable to move the thread laterally across the face of the contactmember.

Whenever a surface or'a pair of surfaces of any of the contact members25'has become fouled, it is only necessary to give the member a partialturn to bring up a fresh set of surfaces, whereby the machine may bekept running continuously. It is a simple matter to' clean the fouledsurfaces after themembers have been thusturned" to bring fresh surfacesinto operation. It will also be noted that, becausethethreads pass overthe contact surfaces from left to right of the operator as'he standsfacing the side of the machine, the said threads are accessible at alltimes, may be watched at all times, and, should a thread break, suchthread may be readily tied and started again and, furthermore, in firstthreading up the machine, the operator can readily reach every partthereof and can retain control of the thread at all times.
